scsi: ses: Fix slab-out-of-bounds in ses_enclosure_data_process()
In the Linux kernel, the following vulnerability has been resolved: scsi: ses: Fix slab-out-of-bounds in ses_enclosure_data_process() A fix for: BUG: KASAN: slab-out-of-bounds in ses_enclosure_data_process+0x949/0xe30 [ses] Read of size 1 at addr ffff88a1b043a451 by task systemd-udevd/3271 Checking after (and before in next loop) addl_desc_ptr[1] is sufficient, we expect the size to be sanitized before first access to addl_desc_ptr[1]. Make sure we don't walk beyond end of page.
